Again, sorry if I caused offence. Your post did prompt me to examine some other numbers. I wasn''t able to find the formula for vertical center of gravity - presumably it would involve quantifying weight of the mast, etc., something it wouldn''t be a simple task to do. In my research, however, I did find this from Adlard Coles'' Heavy Weather Sailing baseed on his research "The effects of large movements of the VCG on the propensity to capsize was surprising small." I did find the formula for angle of vanishing stability (AVS), and pulling the raw numbers from the original Taipan 28 specs, I calculate it to be 183 degrees - exceptionally good from what I''ve read. L/D (lift/drag, right?) - can''t imagine that would be remarkable for this boat or for any other modified full-keeler, but then we are talking about cruisers not racers, right?
